摘　　要：以2018-2022年大亚湾大气监测数据为基础,分析近五年来空气质量变化情况。结果表明:近五年大亚湾空气质量全年优良率均大于94.2%,满足环境空气质量二级标准;对大亚湾空气质量影响最大的污染物是臭氧,其作为首要污染物的占比高达75.9%~94.7%,臭氧污染主要集中在每年的春秋季节;NO_(2)、PM_(10)和PM_(2.5)近五年来在环境管控措施下改善明显。based on the environmental monitoring data in Daya bay during 2018-2022,the variation of ambient air quality was evaluated in nearly five years.The result indicated that the non-exceedence probability in Daya bay were higher than 94.2%,ambient air quality reached the second class of ambient air quality standards.The pollutant that had the greatest impact on Daya bay ambient air qurlity was ozone,the primary pollutant accounted for 75.9%~94.7%,the ozone pollution was concentrated in the spring and autumn of each year.NO_(2),PM_(10) and PM_(2.5) had improved significantly in the past five years under environmental control measures.
